Hi there,
I believe the answer to this will be B.
Now I was crossed between B and A because the sun is nuclear but the Earth isn't but the Earth has a a lot of chemicals like the sun, and in the plants on Earth what type of energy does it have when it uses the sun as photosynthesis?
Chemicals.
So with that the answer should be chemical
Hope this is correct :)
Have a great day
<u>Answer:</u> The equilibrium concentration of chloride ions in the solution is 4.532 M
<u>Explanation:</u>
We are given:
Initial molarity of
= 0.054 M
Initial molarity of HCl = 4.60 M
Equilibrium molarity of
= 0.034 M
The chemical equation for the reaction of
and HCl follows:
![[CoCl_2.6H_2O]+2HCl\rightarrow H_2[CoCl_4]+6H_2O](https://tex.z-dn.net/?f=%5BCoCl_2.6H_2O%5D%2B2HCl%5Crightarrow%20H_2%5BCoCl_4%5D%2B6H_2O)
Or,
![[CoCl_2.6H_2O]+2Cl^-\rightarrow [CoCl_4]^{2-}+6H_2O](https://tex.z-dn.net/?f=%5BCoCl_2.6H_2O%5D%2B2Cl%5E-%5Crightarrow%20%5BCoCl_4%5D%5E%7B2-%7D%2B6H_2O)
<u>Initial:</u> 0.054 4.60
<u>At eqllm:</u> 0.054-x 4.60-2x x 6x
Evaluating the value of 'x':
![x=0.034](https://tex.z-dn.net/?f=x%3D0.034)
So, equilibrium concentration of
= (4.60 - 2x) = [4.60 - 2(0.034)] = 4.532 M
Hence, the equilibrium concentration of chloride ions in the solution is 4.532 M
70x0.2=5×x
X=2.8 ml
basically for these kind of questions you should use this formula: m1v1= m2v2
m is molar v is volume
Here's one! those spots are actually storms:)
